Furse Earthing and Lightning Protection
and Electronic Systems Protection by Thomas & Betts
Plug-in
Protectors for Telephone & ISDN Lines
 Use
to protect telephony equipment plugged into a BT telephone (BS
6312), Modem (RJ11) or ISDN (RJ45) socket.
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all lines - Full Mode protection
-
Full mode design
capable of handling partial lightning currents as well as
allowing continual operation of protected equipment
-
Repeated
protection in lightning intense environments
-
Supplied in a
sturdy ABS housing ready for flat mounting, or vertically
via TS35 'Top Hat' DIN rail
-
Substantial
earth stud to enable effective earthing
-
ESP TN/JP, ESP
TN/RJ11-2/6, ESP TN/RJ11-4/6 and ESP TN/RJ11-6/6 are
suitable for telecommunication applications in accordance
with Telcordia and ANSI Standards

Telephone Lines
with LSA-PLUS Modules
 Use
on ten line LSA-PLUS disconnection modules to PBX telephone
exchanges, ISDN and other telecom equipment with LSA-PLUS
disconnection modules.
-
Low cost
protection for large numbers of data and signal lines
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all lines - Full Mode protection
-
Full mode design
capable of handling partial lightning currents as well as
allowing continual operation of protected equipment
-
Under power
lines cross conductions /PTC versions offer safe
disconnection during fault duration. The unit will then auto
reset once the fault has been corrected
-
Use the ESP KE10
to provide trouble free earthing for up to ten ESP KT1/2s
and ESP KT1/PTC (per disconnection module)
-
At larger
installations ESP K10T1/2 and ESP K10T1/PTC provide all in
one protection for all ten lines on a standard LSA/PLUS
disconnection modules
-
ESP T1, ESP KT1/PTC
, ESP K10T1 and ESP K10T1/PTC are suitable for
telecommunication applications in accordance with Telcordia
and ANSI Standards

Computer
Networks up to Cat-5e & PoE
 Use
this protector on network cables that travel between buildings
to prevent damage to equipment, e.g. computers, servers,
repeaters and hubs. Suitable for twisted pair Ethernet networks,
including Power over Ethernet (PoE), with RJ45 connections.
-
Suitable for
systems signalling on up to eight wires of either shielded
or unshielded twisted pair cable
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all lines - Full Mode protection
-
Unlike some
competing devices, the ESP Cat-5 Series provides effective
protection without impairing the system's normal operation
-
Low capacitance
circuitry prevents the start-up signal degradation
associated with other types of network protector
-
Low in-line
resistance minimises unnecessary reductions in signal
strength to maximise signalling distance
-
Supplied with
short (25cm) Cat-5e UTP cable to enable neat installation

Local Protection
for Computer Communications
 Use
on cables running within a building to protect equipment locally
from transients induced onto data cables from the magnetic field
caused by a lightning strike.
-
Let-through
voltage below equipment susceptibility levels
-
Negligible
in-line resistance
-
ESP LA-5/25
protects pins 1, 2, 3, 7 and 20 to earth/shell. Note pin 1
is connected to earth
-
ESP LA-25/25 and
LB-25/25 protects all pins. Note pin 1 is connected to
earth/shell
-
ESP LA-9/9, ESP
LB-9/9, ESP LA-15/15 and ESP LB-15/15 protect all pins
-
Male/female
connectors allow easy plug-in installation without rewiring

Local Protectors
for Internal Cabling up to Cat-5
 Use
on network cables running within a building to protect systems
locally from transients induced onto data cables from the
magnetic field caused by a lightning strike. Suitable for
internal twisted pair applications using Cat-5 wiring and RJ45
connectors.
-
Suitable for
systems signalling on up to 8 wires of unshielded twisted
pair cable - protects all 8 pins in each line
-
Suitable for RS
422/423, 10baseT, 100baseT, Token Ring and Fast Ethernet
systems
-
Use to protect
1, 4, 8 or 16 lines
-
Available for
individual connections or for multiport applications
-
Protects twisted
pair lines operating at speeds up to 100Mbps
-
Available as 4
or 8 port free standing versions (ESP LN-4 and ESP LN-8) and
8 or 16 port 19" rack mounted panels (ESP LN-8/16 and ESP
LN-16/16)

Coaxial Ethernet
Protectors
 Use
these protectors on thick and thin Ethernet cables that travel
between buildings to prevent damage to equipment, e.g.
transceivers, servers and repeaters.
- Very low
let-through voltage (enhanced protection to BS EN 62305)
between all lines - Full Mode protection
- Very low
reflection coefficient/VSWR
- High
bandwidth prevents degradation of high frequency signals
- Low in-line
resistance to minimise unnecessary reductions in signal
strength and maximise signalling distance
